Some CFD solvers are developed for certain applications but not practiced on large scales of industrial problems.Example: ANSYS FLUENT, STAR CCM, and OpenFOAM.Many industries have compared their plant (practical) data with CFD results.These solvers have been used in many industries and well-practiced numerical models are available there.In the last four decades, CFD solvers have been developed for a wide variety of complex flows like turbulent, multiphase and combustion etc.Multiscale and multi-domain: there can be multiple scales in the system like battery.Fixed or moving boundaries: Moving or stationary walls in turbo-machinery.Other flow physics: Magnetic or electric field acting on the fluid.Multi-phase flow like boiling or condensation.single-phase: Example – air flow through pipe.Phases of material: One or more phases can interact each during flow.
Reaction in the flows: Passive flow in pipe or duct. Heat and mass transfer: Conduction, Convection, and radiation heat transfer. Fluid mechanics: Properties of fluid, Laminar, and Turbulent Flow. Numerical Methods: finite volume method (FVM), finite element method (FEM), finite difference method (FDM). Partial differential equations, integration. Hence, C FD users have to be familiar with the following subjects as per their specific requirement. 
Computational fluid dynamics (CFD) is an interdisciplinary subject. Post-processing and results analysis: Predicted physical quantities need to be analyzed qualitatively and quantitatively. 
Simulation: Solving governing equations over a meshed model. Pre-processing: Creation of geometry and meshing. Computational fluid dynamics (CFD) comprises majorly three steps:. After solving iteratively using computer programs, engineers visualize predicted velocity, pressure and temperature. Numerical methods are used to convert partial differential equations in to algebraic set of equations. Governing equations are conservation of mass, momentum, heat and mass transfer. Computational fluid dynamics (CFD) is a technique of flow predictions by numerically solving governing equations of fluid flows. What is Computational Fluid Dynamics (CFD) Definition of CFD Modelings and Simulation is called as a third pillar of science and technology in the 21st century. Using the CFD technique, heat and mass transfer, reactive flow, multi-phase flow and combustion can be analyzed using various numerical models. Computational fluid dynamics (CFD) is a technique of modeling and simulation based on numerical modeling for fluid flow. It is useful to solve real world problems which can not be solved by theory and may be expensive by experimental analysis. Modeling and simulation is a technique to prediction the science and explore new knowledge. Modeling and simulation has emerged as a third pillar in many fields like engineering, molecular dynamics and astronomy. There are many limitations to get solutions for complex problems either by theory and experiments. Carrying out experiments is expensive, risky and time consuming. Experiment is conducted for simple cases to understand the details of objectives. Using theory and mathematical formulation we can solve simple problems in our real life and nature.
